.To all whom t may concern:

Be it known that L'HENRY E. DECKEBACH, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Wort- Coolers, of which the following is a speciiication.

My invention is an improved apparatus for cooling wort. Its object is to provide a simple effective apparatus to be placed between the hop-jack and fermenting-tuns in a brewery, whereby the wort or similar liquid is conveyed from the hop-jack (or the boiler when the hop-jack is dispensed with) to the fermenting-tuns, the liquid passing through air-tight conveyers. By this means loss by evaporation is prevented, the aroma of the hops retained, and deleterious germs, with whichthe atmosphere is laden, excluded, and the wort gradually cooled on its passage through the cooling-conduits. These ends I attain by the means illustrated in the accompanying drawings, in connection with which the invention will be first fully described, and then particularly referred to and pointed out in the claims.

The apparatus as illustrated is arranged with the different sections in the same horizontal plane in order that it may be conveniently placed directly under the hop-jack for the purpose of economizing space; but it is obvious that they may be arranged in dierent planes or stacks without varying the result intended.

Referring to the drawings, in which like parts are indicated by similar reference-letters wherever they occur throughout the various views, Figure l is an end elevation of an apparatus embodying my invention. Fig. 2 is a top or plan elevation of the same, the intermediate sections being broken away. Fig. 3 is a' central horizontal sectional view of the device upon an enlarged scale, the central section being omitted. Figs. 4 and 5 are detailed views, in central vertical section, of

the meeting ends of the branch pipes which vconduct one of the cooling agents from one section to another. Fig. 6 is a view in longitudinal section of the filtering or finishing section of the apparatus similar to the view shown at the right of Fig. 3. Fig. 7 is an end.

View, upon an enlarged scale, of the same with the cap and discharge branch removed.

Fig. 3 is a transverse sectional View of the i rpipes for the cooling agents in elevation. Fig.

10 is a `central longitudinal sectional view taken at a right angle to the view shown in Fig. 9. Fig. 1l is a view in longitudinal section of the receiving end of the apparatus shown at the left' side of Fig. 3. Fig. 12 is a transverse sectional view, upon an enlarged scale, taken through line 2 2, Figs. 9 and 10. Fig. 13 is a top view, partly in elevation and partly in section, of a simplified form of my apparatus. Fig. 14 is a detail view of the same in end elevation.

Referring first to Figs. l to 12, inclusive, A represents cylinders, any suitable number of which may be arranged in series, each cylinder having flanged branches a at the inner end and similar branches a at the outer end upon opposite sides, the flanges being perforated to receive screw-bolts by which the Sections are connected. The outer ends of these cylinders have also outwardly-projecting annular flanges which are perforated to receive screw-bolts by which caps a2 are secured, the caps being perforated to pass conduits for the cooling agents. rIhe inner ends of the cylinders A are closed by caps having removable screw-threaded plugs a3.

B is a cylinder having hanged ends, the inner ange being perforated to receive screwbolts which secure the cap b to the end of the cylinder. The cap is centrally perforated and screw-threaded to receive the branch b', upon the inner end of which is secured an elbow b2 to connect with a pipe discharging from the hop-jack. (Not shown.) This cylinder B is provided near its outer end with a anged branch b3, which connects the receiving-cylinder B with the first cylinder A of the series. The outer flange of the cylinder B is provided with inwardly-projecting lugs b4, between which are pivotedswinging bolts, the shafts of which pass into notches in a cap b5, which closes the outer end of the cylinder roo B. These bolts are provided with wing-nuts h6 to secure the cap in position.

B is a cylinder constructed in allrespects like the cylinder B. Its discharge branch 197 conveys wort which is passed through the apparatus to the fermenting-tuns or to an exhaust-pnmp which discharges into said tuns.

lVithin the cylinder B is secured a cylinder B3, formed of perforated sheet metal to strain the wort before it passes into the cooling-sections A, and the cylinder B' is provided with a similar straining-cylinder B1, except that its top is closed by a cap bs, as seen in Fig. 7, which is perforated similarly to the body of the cylinder. W'ithin this cylinder is a filteringcylinder B5, formed of fine wire-gauze or other straining material, the cylinder being supported by the cylinder B4, which is centrally supported within the cylinder B' by guide beads or pins b9. The straining and filtering cylinders in both the pipes B and B may be removed for cleansing by loosening the wing-nuts, swinging the bolts out of the notel1es,and removing the caps b5.

Each of the cylinders A is similarly provided with conduits for the cooling agents, which I will now describe, referring particularly to Figs. 3, 9, and l0, the description of one answering for all.

C is a cylinderarran ged centrally within the cylinder A, having one end extending through the cap e2, the extended end of the cylinder being iianged to connect with the union d ot' the pipe D, which is the conveyer of one of the cooling agents. Within the cylinder C is a plain open-ended cylinder CQ the lower end of which is reduced and secured in the bridge or partition d of the union d, the cylinder C' being centrally sustained within the cylinder C by beads or pins c, as seenin Figs. l0 and l2. The cooling liquid passing through the pipe D rst passes between the cylinders C and C', thence through the cylinder C', and on to the next section of the cooler.

Around the cylinder C,in the space between it and t-he cylinder A, is a double spiral coil E, the coils touching both cylinders, so as to form a spiral path through which the wort is compelled to travel in its passage through the jack between the cylinders A and C. The inner end of the cylinder C terminates in a branch or T-union c', into which the opposite ends of the coil E are secured. The lower end of the coil passes upon opposite sides of the cylinder C through the cap a2. Its lower end, which bends over the cylinder C, is provided with a coupling c. A pipe E passes through the union (l,centrally through the cylinder C, and is screwed into the upper end of the cylinder C, thus communicating through the union c with the coil E. The coils E in the diferent sections are connected, when desired, by branch pipes e', and the pipes E are similarly connected by branches e2.

lVhen it is desired to pass the eoolin g agent from two sources of supply through the Whole apparatus, all of the coils E and pipes E are coupled together by the branches c and c2, and the iiow through the pipe D, unions d,

and around and through the cylinder C is continuous; but if more rapid cooling is desired I have provided means for introducing a cooling agent or agents independently to two or more sections of the apparatus and employing different cooling agents foreach pair of sections. By this means I may use three or more cooling agents-for instance, ammonia, brine, cold water, or cold air. I have arranged the apparatus so that it may be readily changed to employ either one, two, or more cooling agents. For this purpose the flanged branches of the union d may be provided, one or more of them with laterally-projecting nipples, which are closed when the flow through the pipe D is to be continuous by plugs d2, as shown in Figs. 2 and 4. The continuous fiow through the pipe is cut off by placing the sheet-metal disk or partition d3, Fig. 5, between the flanges on the branch of union d, removing the plugs LZ2, and securing in the nipples an inletpipe d1 upon one side of the partition and an outlet-pipe d5 upon the opposite side. These removable plugs d2 are only shown between two pairs of sections in Fig. 2, but they may be duplicated between each alternate pair of the apparatus.

To cool the coils E independently in each pair of sections, the branches e are removed and an inlet-pipe connected to one of the nipples c, as the right-hand coupling in Fig. 2, and a discharge-pipe connected to the adjacent coupling and so alternately to the wortreceiving end of the apparatus, it being understood that the cooling liquid flows in a direction contrary or against the flow of the wort, so that whether the cooling liquids pass in a continuous flow from the wort-discharge end of the apparatus or different cooling agents are used from the discharge to the wort-receiving end the cooling is gradual,tl1e warmer cooling agent comin g in contact with the wort when it enters the first section of the series and the wort coming in contact with the liquid in its coolest state in the last section, or the one next to the filter B. It is, of course, obvious that either of the branches e or e2 might be removed. lf the branches c2 were removed, the inlet-pipe would be connected to the extended end of the pipe E of the first section and the outlet-pipe to the next section to it, and so on through the series, if desired.

The cylinders A being all alike, as are also the cooling-conduits therein, it is obvious that any number of sections may be employed in an apparatus, depending upon the amount of wort to be cooled, and also that the sections may be arranged side by side, as shown, or any number ot' them in stacks, one above the other, without material change in the parts except as to position.

In some cases it is found desirable to introduce filtered air into the wort while passing through the cooler. When this is desired, one or more of the plugs a3 may be removed from the top of the cylinder A and the pipe for conveying purified or filtered air secured in place thereof.

In the modified form of myinvention shown in Figs. 13 and 14 the pipes E andthe inner cylinders C' are omitted Vand the protruding ends of the cylinders C provided with couplings c for connecting the sections by means of branch e2 and the discharge-pipes for the cooli-ng agent; but the receiving-cylinder B, instead of being placed at one end of the device, as shown in the preceding figures, is placed centrally between the sections, so as to be more conveniently connected to the hopjack, and the end section upon one side of the cylinder Bis connected to the first section upon the opposite side by a pipe A/ and elbow-unions a4. The exhaust-pump F (shown in Fig. 13) is of ordinary construction, and any ofthe Well-known exhaust-pumps may be employed When an Vaccelerated How of the Wort is desired.

I have found by experience that better results are produced by compelling the Wort to travel in a spiral path in contact with the cooling-surfaces in the jacket between the outer and inner cylinders; but I do not wish to be limited to this specific construction, as it is obvious that the same result in vkind would be obtained by compelling the wort to travel in a zigzag or other sinuous path through the different sections.

What I claim is'- 1. A Wort-cooler composed of a series of similar sections connected together, each section composed of anon' ter and inner cylinder forming a Wort-jacket between said cylinders, conduits for the cooling liquid in said jacket, around Which the Wort flows, a strainer at the Wort-receiving end of the cooler, and a lter at the Wort-discharge end of the cooler, induction and eduction pipes conveying the cooling agent through the sections in the opposite direction from the flow of 'the wort, combined and arranged substantially as shown and described.

2. The combination, substantially as hereinbefore set forth, of the cooler composed of similar sections containing pipes for the cooling agent, and continuous passage for the Wort around said pipes, a strainer connected to the iirst section of the series, said strainer consisting of an outer cylinder and inner perforated cylinder to receive the Wort and strain it before passing into the space between the inner and outer cylinders, a branch from strainer leading to the hop-jack, a filtering cylinder connected to the last section of the series, consisting of an outer cylinder, an inner perforated cylinder closed at the bottom and filtering material such as described within said perforated cylinder, a branch from said strainer leading to an exhaust-pump for drawing the wort through the cooler, substantially as shown and described.

3. The combination in a wort-cooler of a strainer consisting of an outer cylinder provided with a removable head, an inner perforated cylinder sustained Within the outer cylinder, leaving the space between the cylinders for the passage of the Wort, and a discharge branch leading from said space to the cooler, substantially as shown and described.

4. The combination of the cooler, a filter connected to the wort-discharge end of Asaid cooler, said filter being composed of an outer cylinder, an inner perforated cylinder sustained within said outer cylinder, leaving a space between the two cylinders, said inner cylinder being closed at the top and open at the bottom, filtering material such as described within and supported by said perforated cylinder, a branch for connecting said filter to the cooler at one end, and a branch for conveying the wort from the lter at the opposite end, substantially as shown and described.

5. A section for a wort-cooler consisting of an outer cylinder having an inlet for the Wort near one end, and an outlet near the opposite end and upon opposite sides of the cylinder, an inner cylinder for the cooling liquid forming a jacket with the outer cylinder and eX- tending beyond it, a double-coiled pipe forming a spiral path in the jacket between the outer and inner cylinders, having its oppo site inner ends communicating With the inner cylinder and its looped end Which extends beyond the outer cylinder provided with a coupling to receive either an inlet or outlet pipe for the cooling liquid, substantially as shown and described.
